What is Klaviyo?

Klaviyo is a unified customer platform that helps you build stronger relationships with your customers by giving you full control over your data and interactions. It tracks shopper behavior across your site—what they click, where they drop off, and what drives them to buy. With this insight, you can create and automate personalized emails and SMS messages—like cart reminders, price drop alerts, and product recommendations—using Klaviyo’s built-in templates and workflows. It integrates seamlessly with your tech stack and scales with your growth.


Smart Cart App Overview

Capture high-intent shoppers’ phone numbers and add them to Klaviyo lists to grow your engaged subscriber base. The Klaviyo SMS Capture Smart Cart App is embedded directly in the cart drawer to make it easy to scale lists and then send hyper-personalized text messages with Klaviyo SMS.
